Abstract:

The main emphasis of this report is on the application of nonlinear filtering techniques to state estimation of radiating targets in range-denied systems. The mathematical model for the measurements and the target dynamics is derived, with emphasis on the development of a simplified model for the correlated errors introduced by the inertial reference unit. The nonlinear estimators considered triangulation, extended Kalman filter, and Gaussian second-order filter are evaluated using linearized covariance and Monte Carlo methods. Large initial errors often resulted in poor performance for the extended Kalman filter, while the Gaussian second-order filter provides acceptable performance.
